A Study of GS-3242 in Combination With Lenacapavir Versus Biktarvy in Virologically Suppressed People With HIV-1

The study will have two parts: Part A and Part B. In Part A, the goal of the study is to compare the effectiveness of switching to the study drugs GS-3242 plus Lenacapavir (LEN) versus continuing Biktarvy (bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF)), in virologically suppressed people with HIV-1 (PWH) in treatment Group 1, 2 and 3 at Week 35. In Part B the goal of the study is to compare the effectiveness of switching to the study drugs, GS-3242 and LEN versus continuing B/F/TAF in Groups 4 and 3 at Week 26. The primary objective of part A is to evaluate the efficacy of switching to intramuscular (IM) GS-3242 plus IM LEN versus continuing on B/F/TAF PWH who are virologically suppressed in treatment Groups 1, 2, and 3 at Week 35 and Part B is to evaluate the efficacy of switching to IM GS-3242 plus IM LEN versus continuing on B/F/TAF in PWH who are virologically suppressed in Treatment Groups 4 and 3 at Week 26.

Trial to Evaluate the Safety and Immunogenicity of Priming Regimens of 426c.Mod.Core-C4b and Optional Boost Regimen With HIV Trimer BG505 SOSIP.GT1.1 gp140, Both Adjuvanted With 3M-052-AF + Alum in Healthy, Adult Participants Without HIV

The clinical study is designed to evaluate the ability of two priming vaccine regimens to activate and induce the maturation of cross-reactive CD4 binding site (CD4-bs) antibodies, including VRC01-class antibodies. VRC01- class antibodies are highly desirable to elicit via vaccination because they have broad cover all clades of HIV and passive administration of VRC01 monoclonal antibodies has been demonstrated to prevent acquisition of susceptible HIV strains in clinical trials. The study will assess whether B cells expressing VRC01-like B cell receptors proliferate following immunization with a 'germline-targeting' recombinant Env immunogen. The study will also test whether an immunization strategy based upon fractionated dose delivery of the immunogen may improve the maturation of VRC01-class B cells when compared to traditional bolus dosing. In addition, the study will test whether alterations in the dose of the subsequent boost immunizations affects VRC01-class B cell activation and the rate of antibody affinity maturation. The primary hypothesis of the optional boost regimen is that BG505 SOSIP.GT1.1 gp140 adjuvated with 3M-052-AF + Alum is safe and well-tolerated and will further mature B-cell lineages elicited by 426c.Mod.Core-C4b priming regimens.

Thetha Nami Ngithethe Nawe ("Let's Talk"): Step Wedge cRCT of Peer Led Community PrEP and SRH for Youth in South Africa

Study Hypothesis: Social mobilisation will attract and engage young people into decentralised sexual reproductive health (SRH) services where HIV prevention is tailored to need. Decentralised risk informed (differentiated) biosocial HIV prevention will reduce the overall prevalence of sexually transmissible HIV amongst young people aged 15-30. Study aims: 1. Measure the impact of social mobilisation into decentralised SRH services that provide tailored HIV prevention on the prevalence of transmissible HIV. 2. Evaluate the acceptability, practicability, and reach of social mobilisation and decentralised SRH with tailored HIV prevention to deliver differentiated biosocial HIV prevention. Study design: A step-wedge cluster randomised control trial comparing the effect of the Intervention (social mobilisation by peer navigators into mobile nurse-led SRH clinics) with Standard of Care (SoC) at Primary Health Care clinics, in reducing the proportion of 15-30 year olds with sexually transmissible HIV and increased uptake of risk-informed (differentiated) HIV prevention Intervention: Peer navigator social mobilisation intervention includes safe spaces, structured psychosocial and health needs assessment; Peer-mentorship with tailored health promotion, psychosocial support and lay-counselling; provision of condoms, HIV self-tests and pregnancy tests. The mobile SRH clinics provide sexually transmitted infection (STI) care, contraception, HIV testing and antiretroviral therapy (ART) if positive and Pre-Exposure Prophylaxis (PrEP) for those eligible (based on national guidelines) and negative. SoC at Primary Health care clinics includes, contraception, HIV testing and ART if positive and PrEP for those eligible and negative. Population: The eligible population are \~26,000 15-30-year-old residing in 40 administrative areas (clusters) of the uMkhanyakude district in rural KwaZulu Natal. The 40 clusters will undergo a stratified randomisation to early versus delayed intervention roll out. Data collection: Research data will be collected from four sources: i) three random representative surveys of n= 2000, 15-30-year-olds; ii) programme, process, and clinical data; iii) qualitative data collected during the process evaluation iv) cost data using bottom-up ingredient-based costing and top-down costing using the budgets and expenditure reports. Study Duration: 36 months.

Tesamorelin as an Adjunct to Exercise for Improving Physical Function in HIV

People with HIV experience earlier impairments in physical function compared to people in the general population. They also exhibit an earlier presentation and more rapid development of frailty, a multisystemic syndrome of aging characterized by reduced activity, fatigue, slowness, weakness, and weight loss. While exercise can improve physical function in people with HIV, it is less effective in doing so than in the general population and is difficult to sustain in the long-term. The goal of this clinical trial is to learn whether the medication tesamorelin will improve physical function and muscle health in adults with HIV when combined with exercise. Tesamorelin is a growth hormone-releasing hormone analogue that is FDA-approved to treat abdominal fat accumulation in people with HIV. While tesamorelin has also been shown to increase muscle mass and improve measures of muscle health, its effects on physical performance and muscle strength have not yet been evaluated. During a 24-week intervention phase, half of participants will be randomly assigned to receive tesamorelin and half of participants will be randomly assigned to receive placebo (a look-alike substance that contains no drug). All participants also will engage in a home-based exercise intervention supervised by an exercise coach. During a subsequent 24-week extension phase, individuals will be monitored off study drug and supervised exercise, and be encouraged to continue to exercise independently. The investigators will investigate effects of tesamorelin on physical function, muscle mass and quality, quality of life, and exercise adherence and self-efficacy. They also will evaluate whether effects of tesamorelin are maintained following treatment cessation. This study may identify an important strategy to improve how individuals aging with HIV function and feel with potential applications to other patient populations.

Cannabis Use, Cognition, and the Endocannabinoid System in HIV

Understanding how co-morbidities in persons with HIV (PWH) such as substance use affect risk-taking, decision-making, and other cognitive behaviors is important given implications for everyday functioning and transmission risk. The high prevalence of cannabis use in PWH, medicinally and recreationally, may indicate disease severity, impart therapeutic benefits, or adverse consequences. In fact, cannabis is recommended to those with HIV to alleviate nausea, improve appetite, relieve pain, and lift mood. To-date, the consequences of cannabis use in PWH remain unclear as do potential interactions with HIV treatments. In healthy participants, heavy cannabis use is associated with cognitive deficits e.g., risky decision-making, response disinhibition and inattention, but pro-cognitive effects in PWH may exist at mild use levels due to its anti-inflammatory and anti-excitotoxic properties. Furthermore, little has been done to determine the effects of cannabis use on the endocannabinoid (EC) system in general or in PWH. This study will determine the effects of the two primary cannabis constituents (Δ9-tetrahydrocannabinol \[THC\], cannabidiol \[CBD\]) vs. placebo on risky decision-making, response inhibition, reward learning, temporal perception, and motivation, plus EC and homovanillic acid (HVA; a surrogate for dopamine activity) levels in HIV+ and HIV- subjects. Participants with infrequent cannabis use will undergo baseline cognitive testing and biomarker assays with antiretrovirals (ART) use quantified. They will be randomized to a 5-day course of either THC, CBD, or placebo and return for follow-up testing and re-assaying of ECs and HVA levels.

Study to Compare an Oral Weekly Islatravir/Lenacapavir Regimen With Bictegravir/Emtricitabine/Tenofovir Alafenamide in Virologically Suppressed People With HIV-1

The goal of this clinical study is to learn about the safety and efficacy of switching to once weekly tablet of islatravir/lenacapavir (ISL/LEN) regimen versus continuing standard treatment of bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) in people with human immunodeficiency virus (PWH) who are virologically suppressed (HIV-1 RNA levels \< 50 copies/mL) on B/F/TAF for ≥ 6 months prior to screening. The primary objective is to evaluate the efficacy of switching to oral weekly ISL/LEN tablet regimen versus continuing B/F/TAF in virologically suppressed PWH at Week 48.
